Implementation Reference
- src/waf_mcp/server.py:96-102 (handler)The handler function for the 'waf_reload_rules' tool. It calls _reload_engine() to reload rules from disk and returns a success response with stats.
@mcp.tool def waf_reload_rules() -> Dict[str, Any]: """重新从磁盘加载 WAF_RULES_FILE（或默认 rules/waf_rules.mcp.json）并编译。用于修改规则文件后无需重启 MCP。""" eng = _reload_engine() stats = eng.get_stats() return {"success": True, "message": "规则已重新加载", "stats": stats} - src/waf_mcp/server.py:46-49 (helper)The helper function _reload_engine() that creates a new WAFEngine instance (loading rules from disk) and replaces the global engine.
def _reload_engine() -> WAFEngine: global _engine _engine = WAFEngine(str(_rules_path())) return _engine - src/waf_mcp/server.py:97-97 (registration)The @mcp.tool decorator that registers 'waf_reload_rules' as an MCP tool on the FastMCP instance.
@mcp.tool - src/waf_mcp/server.py:98-102 (schema)The return type Dict[str, Any] defines the schema: it returns a dict with 'success' (bool), 'message' (str), and 'stats' (dict from get_stats). No input parameters needed.
